Modified cognitive behavioral therapy is an integrated treatment approach that focuses on relapse prevention and motivational interviewing techniques. Patients are guided in enhancing their problem solving and social skills, and are taught how to manage triggers, cravings, and the unique difficulties they may face as an individual with comorbid disorders. Building of these skills is exercised in structured small group sessions twice a week for around 6 months, and accommodates potential cognitive limitations of schizophrenia by only focusing on a small number of skills. This therapy approach also uses positive reinforcement, through strategies like giving the patient a small amount of money, for drug-free urine test results.
